Dungeon Buster · One Up Plus — Indie games from Sydney, Australia

Dungeon Buster is an incremental dungeon-building extraction autobattler RPG. Build the dungeon, send in your hero, and turn every successful expedition into permanent power. Expand a mysterious underground stronghold room by room. The paths you create determine what your hero discovers, which dangers they face, and how deep they can travel before returning with their spoils.

Build. Battle. Extract. Improve.

Your hero explores and fights automatically, using the equipment, spells, potions, and skills you prepared. Watch them clear rooms, overcome traps, collect treasure, and decide whether to continue into the darkness or return safely. A failed expedition can cost you what you have not secured. A successful extraction brings resources back to the Workshop, where they fuel permanent upgrades and an even larger dungeon.

The dungeon is your progression

Every room you add creates new routes, encounters, rewards, and risks. Unlock new construction options, discover special rooms, break the Wardens’ seals, and prepare your hero for the Guardian waiting at the dungeon’s heart. Combine equipment effects, active abilities, passive skills, and permanent upgrades to create increasingly powerful runs and increasingly dangerous opportunities.
